Description
Technical field
The present invention relates to a kind of Petroleum Down-hole Tool, more particularly to a kind of drill bit.
Background technology
Drill bit is the common tool of production wellbores in oil drilling, and in the prior art, drill bit is generally connected to bore
Column bottom, rotation torque and pressure are provided by drill string, the cutting to formation rock are realized, so as to form well
Eye.After borehole size is small to certain size, and borehole depth reaches certain size, drill string due to flexing,
Cannot transmitting torque the pressure of the drill, thus conventional bit and its application method cannot meet fine well (borehole diameter is small
In 20mm) demand of drilling well.Although in consideration of it, all kinds, the brill of specification of current oil drilling
Head category is numerous, but not used for the drill bit of fine well drilling well.
The content of the invention
A kind of part in view of the shortcomings of the prior art of the invention, it is proposed that drill bit.
According to a kind of drill bit that the present invention is provided, including：Drill body, the first end of drill body includes impeller,
And the section that second end relative with the first end of drill body is connected.Wherein, drill body includes being arranged on
The blind hole at the second end of drill body, is further opened with multiple flowing holes, and each flowing hole on the periphery wall of body
It is connected with blind hole.
According to the drill bit that the present invention is provided, the drill bit has abandoned drilling tool of the prior art and has transmitted torsion using motor
Square simultaneously realizes the mode of the pressure of the drill, but employs fluid driven impeller and realize the mode that drill bit occurs spinning
Applying to torque-on-bit and the pressure of the drill, so that the production fine well of oil is achieved.In brill of the invention
During the use of head, the first end of drill body is connected with external pipe, is driven by the fluid in external pipe
The impeller of the first end of drill body rotates, when fluid is flowed by the inner chamber of the larger external pipe of area of passage
When moving the less flowing hole of area of passage and blind hole, drill body is set to produce chock pressure difference, in this chock pressure difference
In the presence of drive section to rotate, the formation rock for making section pair be contacted with it carries out the pressure of the drill, cut so as to reach
Cut the effect of contact formation rock.
In some embodiments, drill body is the cylindrical body that round platform is provided with circumference, and each flowing hole
With the same side that impeller is located at round platform.The round platform is used to be connected with external pipe, while the round platform is by drill body
Two parts are separated into, so that the part for being provided with each flowing hole and impeller positioned at the same side of round platform is placed separately
In external pipe, so as to ensure that fluid flows into flowing hole to greatest extent, the normal of drill bit is effectively guaranteed
Work.
In some embodiments, the hooking ring for being connected with external pipe, external pipe are provided with round platform
Between hooking ring and round platform.The hooking ring can ensure the round platform of drill body and the connection of external pipe, example
As hooking ring is attached with external pipe by screw thread, so as to efficiently avoid drill body and external pipe
Disengagement.
In some embodiments, seal is additionally provided between external pipe and round platform.It is right that the seal is used for
Sealed between drill body and external pipe, it is ensured that fluid can only be flowed on drill body by external pipe
Flowing hole, and by blind hole flow out.
In some embodiments, each flowing hole is evenly distributed on the periphery wall of drill body.Uniform point
The flowing hole of cloth makes the pressure produced at flowing hole evenly, so that the work of drill bit is more steady.
In some embodiments, the center overlapping of axles of the central shaft of blind hole and drill body, in each flowing hole
Heart axle is acute angle with the angle of the central shaft of blind hole.By this set, fluid is easier to enter flowing hole and produce
The larger pressure of life, so as to the operating efficiency of drill bit can be improved.Preferably, the central shaft and blind hole of each flowing hole
Central shaft angle it is identical, the program can lifted bit operation efficiency while ensure the steady of its work
Property.
In some embodiments, frustum is formed between impeller and flowing hole.The frustum is provided for fluid
The circulation path of more steady and smooth, is conducive to the stability of flow of fluid, so as to improve the stationarity of bit operation.
In some embodiments, the second end of drill body also includes fixing groove, and section is located in fixing groove.
The fixing groove is conducive to the fixation and replacing of section.
In some embodiments, the fixing end of section is in contact with the side wall of round platform.In this scenario, cut into slices
The side wall of round platform is extended to, the rigidity of section is improve to a certain extent, it is difficult hair while rotation
Life fractures, in addition, the setting also improves the compactedness and aesthetic property of the structure of drill bit.
Compared with prior art, drill bit of the invention realizes applying for drill bit the pressure of the drill and moment of torsion using fluid matasomatism
Plus, so that the production fine well of oil is achieved.
